As Luke Ayling and Gaetano Berardi are both injured, left-back Douglas returned to the side after returning from his own injury lay-off. He played for the under-23s against Hull on Monday to boost his match fitness ahead of this one.

He replaced Ayling who suffered medial collateral ligament damage to his knee in the draw to Nottingham Forest on last weekend and is expected to miss months.

Meanwhile, Kemar Roofe once again heads the United attack and will be hoping to continue his fine form of late where he has netted two in two.

Star man Pablo Hernandez starts, as does Adam Forshaw, with Samuel Saiz once again needing to make do with a place on the bench.

Douglas has not featured since the win at Hull

Bielsa said of Saiz ahead of this one: "Samu Saiz is a great player.

"He is the player who can create the lack of balance that our team needs. He’s the only player in our group who can create this lack of balance.

"Taking into account what he did so far this season and what he did last year because I saw the games he played last year too. I’m not making an opinion about last year, it’s just I saw how he played last year and I can talk about him.

"He’s not playing because he’s going ups and downs and things like this happen in a competition with 46 games.
